Product Description

?

This is a genuine OEM sourced replacement part used on gas trimmers/edgers. The purpose of this part is to mix air and gas before the fuel mix goes to the engine. If the engine won't start and the tank is full of fresh fuel, test the carburetor by removing the air filter and pouring about a teaspoon of fuel into the carburetor. Pull the starter rope. If the engine starts and then quickly dies, the carburetor is likely the problem. This is a metal body carburetor, it is sold individually. This assembly includes fuel lines, primer bulb. You will need a screwdriver to perform this repair.

Easy Repair!
Less than 5 minutes and my 12 year old string trimmer was running like a top again. Watched a quick repair video and the fix was so simple! I have the satisfaction of fixing it myself and saved over $200 in repairs!

The carburetor fit perfectly and was an identical match for the original part. This purchase turned a useless string trimmer into one that worked like new!

It would be better to provide new fuel lines and keep the line splicing connectors.

Great part, Great customer service.
I received the carburetor, installed it and it worked great. However the next day the primer bulb would not pop out. Seemed like a vacuum was holding it in. I called Customer Service, and the woman was very helpful, she found the problem was very unique and wasn't in her troubleshooting guide. She sent out another one and provided me with a prepaid return label to return my defective one. As easy as that.

Spark plug was good and getting spark. Fuel was clean with no trace of moisture. Tines were clear of vines and weeds. Good compression and full of oil. Spark shield was clean and clear. This left only a fuel problem. Replaced carb ( no kit available ) filled with new fuel and it started right up. Hope to get five more years of great servi ce out of machine.

Troybuilt TB146 EC tiller - four stroke
1.) Removed the 4 - 5 top cover screws
2.) Removed the air breather cover, filter and filter grate, and assembly. See the spacers in the housing for the long bolts put them back, a big help to have.
3.) Removed the carburetor.
4.) Disconnected the throttle connection from the carburetor.
5.) Lift and discounted the throttle cable securement from the body of the motor, use two standard screwdrivers to push in on both sides of the holder, it just lifts off and out of the way.
6.) Remove the carburetor gasket, big cardboard piece. Remember to tuck in under the plastic housing when reinstalling
7.) Remove and reinstall the spark plug if needed, did they come pre-set, the carb too.
8.) Re-install in reverse.
9.) Change the oil while you are there. Do not overfill or it will run out of the air breather assembly.
10.) The power bit starter is great, all small engines should have one of these. A standard square bit, I bet would work too.

Easy to replace carb, but I did trim the plastic flanges in the air filter housing to allow easier re-installation of two nuts. Also I locked the two nuts together to remove and re-install the air filter mounting screws.
